To a/ZZ whom it may concern: s Y, Y c .Be it known that I, EDWARD E.` GOLD, a citizenof the United States, residing in the borough of Manhattan, city, county, and StateV of 'NeWYork, have invented certain new and useful Improvements in Heaters, `of which the following is a specification. v

. This invention alms toprovide certain'improvements in the type of car-heaters indicated in my prior patents, Nos. 388,772, of August 28, 1888; 571,359, of November l17, 1896, and others. In this type of heater a coilis carried within a casing constituting, in effect, a stove, the endsof the coil being con-- nected to the circulating radiating. system extended throughoutthe car, the heatingof the coil serving to cause the desired circulation. radiating system is arranged toV be heated either by steam or by a fire built in the lower part of the casing or stove limmediately under the coil. The invention, however, in

its broadest conception is ap licable to any heater in which a coil is carrie in a casing fitting close around the coil, the improvement being infea'turesof construction which facilitate the assembling of theparts and which make itpossible to use for a given diameter of coil a casin lconsiderably smaller than has been possib e with the previous constructions and4 Which presents certain other advantages referred to in detail hereinafter.

AIn previous constructions the casin has consisted of a .cylinder or cone comp etely closed all around its circumferencethat is to say, Without an open vertical joint. The

introduction into sucli a casing of ja coil having its ends projecting suiiiciently beyond the 'elrcumference of the helix to permit the making' of the necessary outside pi e-.joints has necessitated either that .the co` be of such small diameter as compared Vwith that of the casing as to permit the canting'of the coilv speieation of Letters Patent.

The circulating liquid in the coil andv so that a coil substantially filling the casing canbe introducd with ease, its ends being arranged to roject throughv the open vertical joint, whic can be afterward closed. Preferably a complete section of the casing, such as a vertical strip thereof, is formed separately from the remainder, this section being vpassed over the ends of the coil and this section and the coil being then putinto place at the same time and the section fastened to the .remainder of the casing to complete it.

.The accompanying drawings illustrate a.

vvation.A Fig. 2 is a view at right angles to j Fig. 1, on a slightly largerscale, showing the heater .assemb ed and efore connecting the circulating-pipes. Fig. 3 is a section of Fig. 2 'on the line 3 3.' Fig. 4 is a plan before the application of the coil. Fig. 5 is an enlarged sectional view of one en d of a coil.

Y Referring tothe embodiment illustrated,

- Patented March 2o, 1906.

A represents as awhole a double duplex coilthat is to say, two separate coils each consisting of a lduplex pipe having an inner small steam-pipe surrounded by an outer large. Water-pipe. The steam enters from. the train-pipe B to one or both of the small pipesv C andV D to heatthe water in one or both halves of the radiating system, the lsteam being exhausted from the small pipes E and F and the trap G, or when. a firel is builtin the fire-box H of the heater, there beinglno steam-supply, the Water in the coils is heated and by a suitable system of valves is circulated through one or both halves ofthe radiating system, passing from VTs J K to an overhead tank L, thence through the radiat-` ing system, and finally back into the coil by way of Ts M N. This is the well-known operation. f j

. Theouter pipesof the coil are closed at the outer sides of the Ts J, K, L, andrM by means of annular'plugs O, Fig. 5, and packing-glands l?. The inner pipe D projects beyond'the fitting J suliiciently to make an easy connection With the circulating system. With the former construction of an unbroken 'casing it has been impossible to project the ini v the inner pipe within the pipe Q or within the fitting J, (the latter being applied afterward, of course.) The enlargement of the outer diameter of the inner pipedue to the coupling necessitated making this inner pipe quite small in order to leave a suflicient passage for water betwen the two pipes. With the arrangement shown in Fig. 5 of an unbroken inner pipe the latter can be made larger or the outer pipe can be made smaller than with the old arrangement.

Having an open vertical joint or space in the wall of the casing, the coil is introduced endwise and the length of the ends beyond the diameter of the coil is unlimited; In the construction shown the two free vertical edges R of the casing proper are sufficiently separated to accommodate freely the ends of the two coils alongside each other, as indicated in Fig. 3, and the space between the vertical edges R is bridged by a plate or section S, which is formed separately from the remainder of the easing and afterward bolted or otherwise attached thereto. For the sake of convenience the two upper ends of the coil come out at the same side as the two lower ones, the four ends being passed through suitable holes in the plate S. The plate S, with the attached coil, is then slid longitudinally into place and connected, as by bolts T, to the edges R R of the body U of the casing, the edges R being thus drawn togetherand joined by the plate.

It will be seen that this construction facilitates very much the assemblage of the parts and puts no limitation whatever upon the relative sizes of the coil and casing orupon the length of the ends of the coils or the arrangement of the connections. Consequently the joints are better made and the entire constructionis cheaper. whenever necessary is also facilitated by reason of their accessibility.

Though I have described with great particularity of detail an apparatus embodying the invention, yet it is not to be understood therefrom that the invention is limited to the specific apparatus disclosed.

Various modiiications thereof may be made in detail and in the arrangement and combination of the parts by those skilled in the art without departure from the invention.

What I claim is` 1. A heater comprising in combination a casing, and a coil extending continuously substantially from top to bottom Within said casing, the upper and lower ends of said coil being passed through the upper and lower portions of a side of said casing respectively, said casing having a longitudinal section through which the ends of the coil pass and which is formed separately from the remainder, said coil being entirely supported by said The repairing of joints separately-formed section, and said entire coil with said section attached thereto being adapted for insertion into place or removal by an. endwise movement thereof with respect to the casing.

2.' A heater comprising in combination a casing, and a coil extending continuously substantially from top to bottom within said casing, the upper and lower ends of said coil being continuous without joints inside the casing and being passed through the upper and lower portions of said casing respectively, said casing fitting substantially around said coil and having a vertical joint through which said ends pass, the entire coil being adapted for insertion into place or removal by an endwise movement thereofwith respect to the casing.

3. A heater comprising in combination a casing, and a coil in said casing made of two pipes one within the other, said coil having an end passing through a suitable aperture in said casing with the smaller pipe projecting out of and beyond the end of the larger, and said casing having a vertical joint through which said end passes, whereby the projecting ends of said coil are unlimited in length by said casing, and said casing fitting substantially closely around said coil and having a smooth inner face, the entire coil being adapted for insertion into place or removal by an endwise movement thereof with respect to the casing.

4. A heater comprising in combination a casing comprising a body )ortion U forming nearly a complete circum erence and having a pair of vertical edges, a separately-formed narrow section S joining said edges, and a coil 'in said casing having its ends passing through said section S, said casing fitting substantially closely around said coil and having a smooth inner face, whereby said coil and attached section may be introduced into place by an endwise movement relatively to said body portion.

5. A heater comprising in combination a casing comprising a body portion U having a pair of vertical edges, a separately-formed section S joining said edges, and a coil in said casing made of two pipes Q and D, the latter within the former, said coil having an end passing through said section S with the pipe D projecting out of and beyond the end of the pipe R, whereby the `)rejecting ends of said coil are unlimited in length by the casing and said casing fitting substantially closely around said coil and having a smooth inner face, whereby said coil and attached section may be introduced into place by an endwise movement relatively to said body portion.
